VALVE-GUARD.

Application filed February 3, 1919.

To all whom t may concern Be it known that I, DAVID D. MORRIS, a citizen of the United States, residing at 354 Grant street, Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Valve-Guards, of which the following is a specification.

My invention relates to improvements in valve guards, and has particular reference to a casing adapted to be locked upon a valve, thereby inclosing the same and preventing the unauthorized operation thereof.

An important object of the invention is to provide a device of the above-.mentioned character7 which is simple in construction, cheap to manufacture, and convenient in use.

Other objects and advantages of this invention will be apparent during the course of the following description.

.In the accompanying drawings forming a part of this specification, and in which like reference numerals are em loyed to designate like parts throughout t e same:

Figure 1 is a plan view of a device embodying my invention;

Fig. 2 is a side elevation of the same;

Fig. 3 is a horizontal transverse sectional view through the device; and,

Fig. Llis a central vertical longitudinal sectional view through the same.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a valve, such as a shutoff valve in a gas supply pipe.

My valve guard or casing embodies an upper portion or cap 6, which receives the upper reduced end 7 of the valve. The cap 6 is circular in horizontal cross section, as shown in Fig. 1.

The body portion of the valve is preferably formed in two casing sections 8, which are semi-circular in horizontal cross sec-tion, as clearly indicated in Fig. 3. These casing sections are hinged at their upper ends to the cap 6, as shown at 9, the hinges being preferably arrangedat points equi-distantly spaced from the longitudinal edges of the casing sections 8. The lower ends of the casing sections 8 are reduced and properly shaped to receive the lower end of the valve Specification of Letters Eatent.

Serial No. 274,646.

and the valve stem 10. These lower ends carry extensions l1, having openings'12 receiving the shackle 13 of a pad-lock 14.

The casing sections 8 are provided at their edges with openings 15, receiving the pipe 16, to which the valve is connected. These openings extend through the upper ends of the casing sections, as shown.

From the foregoing description, it will be seen that the casing sections 8 may be swung to an open position and the cap 6 placed upon the top of the valve 5. Subsequently to this operation, the casing sections 8 are swung to the inner or closed position, and

held in such position by means of the padlock 14 or the like.

It is to be understood that the form of my invention herein shown and described is to be taken as the preferred example of the saine and that various changes in the shape, size and arrangement of the parts, may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, what I claim is:

A guard for a valve connected in a pipe with portions of the pipe arranged upon 0pposite sides of the valve, comprising a cap adapted to be arranged upon the top of the valve and to snugly embrace said top, said cap being formed in one piece and comprising a body portion and a depending flange carried thereby, casing sections arranged be rieath the cap and adapted to surround and snugly embrace the body portion of the valve, said casing sections having portions thereof bent to engage beneath the lower end of the valve to prevent upward displacement of the casing secuions, and a portion of the guard inclosing the stem of the valve, means for pivotally connecting the upper ends of the casing sections with the cap, and means to secure the lower ends of the casing sections together toprevent them from being moved apart.

In testimony whereof I ailiX my signature in presence of two witnesses.
